Special protective equipment and precautions for fire fighters

6. Accidental Release Measures

Personal precautions, protective equipment and emergency procedures

Wear protective equipment. Keep unprotected persons away.

Environmental precautions

• Dilute with plenty of water.
• Do not allow to enter sewers/ surface or ground water.

Methods and materials for containment and clean up

• Absorb with liquid-binding material (sand, diatomite, acid binders, universal binders, sawdust).
• Use neutralising agent.
• Dispose contaminated material as waste according to item 13.
• Ensure adequate ventilation.
• Do not flush with water or aqueous cleansing agents.

7. Handling and Storage

Precautions for safe handling

• Ensure good ventilation/exhaustion at the workplace.
• Open and handle receptacle with care.
• Prevent formation of aerosols.
• Information about protection against explosions and fires:
• Keep ignition sources away - Do not smoke.
• Protect from heat.
• Protect against electrostatic charges.
• Keep respiratory protective device available.

Conditions for safe storage

• Requirements to be met by storerooms and receptacles: No special requirements.
• Information about storage in one common storage facility: Not required.
• Further information about storage conditions:
• Keep receptacle tightly sealed.
• Protect from heat and direct sunlight.
• Specific end use(s) No further relevant information available.

8. Exposure Controls / Personal Protection

Exposure Standards

Engineering controls

• Keep away from foodstuffs, beverages and feed.
• Immediately remove all soiled and contaminated clothing.
• Wash hands before breaks and at the end of work.
• Avoid contact with the eyes.
• Avoid contact with the eyes and skin.

Personal protective equipment

Eye and face protection

Tightly sealed goggles.

Skin protection

• Protective gloves
• The glove material has to be impermeable and resistant to the product/ the substance/ the preparation.
• Due to missing tests no recommendation to the glove material can be given for the product/ the preparation/ the chemical mixture.
• Selection of the glove material on consideration of the penetration times, rates of diffusion and the degradation.
• Material of gloves
• The selection of the suitable gloves does not only depend on the material, but also on further marks of quality and varies from manufacturer to manufacturer. As the product is a preparation of several substances, the resistance of the glove material can not be calculated in advance and has therefore to be checked prior to the application.
• Penetration time of glove material
• The exact break through time has to be found out by the manufacturer of the protective gloves and has to be observed.

Body protection

Wear protective clothing.

Respiratory protection

In case of brief exposure or low pollution use respiratory filter device. In case of intensive or longer exposure use respiratory protective device that is independent of circulating air.
